I voted Remain, and that decision makes little sense in retrospect (not none, it was just a lot of the fearmongering turned out to be false).
The bad parts of the EU are far more evident now we are out of it. To most Brits...the EU just seems a bit mad (and did before btw, it was just that many Brits believed the EU would change). I don't think any Brits know what "the good parts" are (again, this was true before 2016 too, we weren't in the EU for "the good parts"...there weren't any for Britain, we didn't need to shed guilt like Germany, we didn't need to use trade barriers to gain competitiveness like Italy or Spain, we didn't need to use to elevate our global profile like France).
Ofc, the points made in the article are nonsensical...but it is the Economist. Saying that Ukraine has demonstrated the importance of Europe is...comic. The economic points are totally illogical...look at Europe's banks, look at the UK's banks, monetary policy, the values are just totally different.
